WIRE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 725,472, dated April14, 1903.

Application filed September 23, 1901. Serial No. 76,165. (No model.)

3 T0 at whom it may concern/.-

Be it known that 1, JOHN H. QDONNELL, a citizen of the United States,residing in the city of Waterbury, county of New Haven, and State ofConnecticut, have invented certain new and useful Improvements inWire-Drawing Machines, of which the following is a specification.

. My invention relates to wire-drawing machines. Y

I will describe a wire-drawing machine embodying my invention and thenpoint outthe novel features thereof in the claims.

In the accompanying drawings, Figure 1 is a top plan view of awire-drawingmachine embodying my invention. Fig. 2 is a transversesectional view taken on the line 2 2 of Fig. 1. Fig. 3 isa longitudinalsectional view, broken away, taken on the line 3.3;of Fig. 2. Fig. 4 isa detail transverse sectional view taken on the line 4: 4 of Fig. 3.Fig. 5 is a detail sectional view. Fig. dis a detail view.

Similar letters of reference designate corresponding parts in all of thefigures.

A represents a table, and A A end legs for supporting the table. Theseparts constitute the main portions of the framework of the machine.

B represents a base part extending longitudinally of the table andhavingits ends fastoned to the legs A'- A C representsthemaindriving-shaft of the machine, which is mounted in suitable bearings0, carried by brackets c, which are suitably attached to or formedintegral with the base B. The. shaft C is provided with .the usualdriving pulley C, loosely mounted thereon, and a clutch, operated by amechanism C or some othermechanism the equivalent thereof, is providedto connect and dis connect the shaft and pulley.

The table A is provided with a longitudinal depressed portion D, forminga tank, which contains a liquid. The tank D is provided with anirregular bottom d, the irregularity being such as to provide fordifferent depths in the tank. The purpose of having the tank D formed inthis manner is to provide a receptacle for the dirt or other foreignmatter in the liquid, and thus have it out of the way around the headsor rolls.

of the wire passing through the dies. The dirt and other matter willsettle in the deepest portion d of the tank and will not be affected bythe circulation of the liquid due to the rotation of the drawing headsor rolls. E represents the drawing heads-or rolls, a detail of onebeing'shown in Fig.5. Each head is mounted and held by a key e uponavertical shaft e, which is mounted and held in a suitable bearing 6',carried by a'bracket 6 which is integral with or suitably attached tothe brace part B. Each head is provided with a sleeve portion 6 toreceive a reduced portion 6 of a shaft 6, and the head or roll is heldon the shoulder e of the shaft by means of a nut c Each shaft Where itpasses through the bottom d of the tank D is surrounded by a bushing e1which bushing extends up to the I sleeve portion 8 to make a tightjoint. All

of the heads or rollsare submerged in the liquid in the tank, thepurpose of which is to better lubricate the heads and wire passing Alsoby having the heads or rolls arranged in a vertical man ner andsubmerged in the liquidthey do not throw the liquid beyond the limits ofthe tank D. Each shaft 6 is provided on its lower end witha bevehgear cand for each bevel-gear 6 there is a gear 63 on the shaft C. The gears cas well as the gears are of diiferent sizes to produce different speedsof the heads or rolls, thereby compensating for the elongation of thewire. A vertical shaft e is also provided for the block E, and thisshaft is rotated by means of gears e and e The gear 6 is removably heldon the shaft 6 in order that another gear of a difierent diameter. maybe substituted. The gear (2 is also adjustable along the shaft 0 tocompensate for the different-size gears e that may be put on the shafte. The purpose of this construction is to obtain different speeds forthe block E. y

In advance of each, head or roll E is a dieholder F, suitably securedwithin the tank D and to the bottom thereof by means of screws f. Eachdie-holder E is of such a height as to have the die carried therebysubmerged.

The die-holder F in advance of the block E is carried in a bracket f,which is hinged or pivoted at f to the bottom of the tank D. The purposeof this is to have the die accommodate itself to the increasing diameterof the block E. The wire before entering the die carried by the bracketf passes about a pulley or roller f journaled on the bracket.

Extending longitudinally of the table A is an opening F forming a runwayfor a gripping device G, employed in stringing dies on a wire. Thegripping device G may be of any desired construction, and it is providedwith grooves or slots in its sides in which flanges g, carried by thetable A, project. Traveling also in this runway is a sprocketchain g,with which a hook 9 carried by the gripping device G, engages. When thishook is in engagement with the chain and the chain is moving, thegripping device will be drawn along the runway. The chain g passesaround an idler-sprocket g and around a drivingsprocket g. The latter isfixed on a shaft g suitably journaled in a bearing g carried by thetable A. The shaft g is also provided with a gear g which meshes with agearg carried by a shaft g", suitably journaled in bearings 9 The shaft9" is provided with a bevel-gear g, which meshes with a bevelgear gcarried by one of the vertical shafts e.

In stringing the machine a sufficient length of wire is drawn throughthe coarsest die, and this die is preferably supported on a movabledie-holder H, having pins h, which fit in openings it, provided in theflanges g. Several openings arranged in pairs are shown in the flangesg, which permit of the holder 11 being' placed in different positionsalong the flanges g. The holder H is also provided with a roll [L2,about which the wire is passed to be in line for drawing through a diecarried by the die-holder II.

I represents a hinged bracket for supporting a roll of wire which is tobe drawn.

The operation of the machine, briefly stated, is as follows: The chain gis started and the block I-I placed in a position on the flanges g. (SeeFig. 1.) The coarsest die is then placed on the block H and a sufficientlength of wire drawn through it to be wrapped or wound about the firsthead or roll, or the first and second heads or rolls, a number of times.The coarsest die is then placed in its holder in the tank D and the wirepassed under a roll or pulley 1} and wrapped or wound about the firsthead or first and second heads, as the case may be. The wire is thenpassed around the roll h of the block H, from the last head or rollabout which the wire has been wound or wrapped, and drawn through thenext coarsest die by the gripping device G. (See dotted lines, Fig. 1.)This operation is continued until all the dies have been strung on thewire, after which the hook of the gripping device is disengaged from thechain. The machine then draws the wire through the dies in the ordinaryway. When stringing the dies on the wire it is preferable that aftereach die is strung on the wire the wire is Wrapped about as manyheads orrolls as possible, in order that they may assist in drawing thenecessary length of wire for stringing other dies. For instance, if twodies had been strung on the wire that portion of the wire on which thedies were strung would be wrapped around the first two heads and the endof the wire wrapped around the third head and carried back to and aroundthe roll 72, on the block II. The die next in order is then placed onthe block H and the end of the wire gripped by the device G. Thegripping device G and the three rolls will then operate to draw enoughwire to string the next or remaining dies on the wire. By reason of theopenings h the block H may be conveniently adjusted to accommodateitself to dilferent lengths of wire projecting upon the last die. Theroll z' and the roll f act to guide and retain the wire on the lowerportions of the drawing heads or rolls in order that the wire will besubmerged at all times during its reduction.

By reason of the head or rolls being submerged, as well as the dies, Iam enabled to operate the machine ata high rate of speed. The submergedhead or rolls or dies will always be well lubricated, and by reason ofthe arrangement of the bottom of the tank dirt in the lubricating liquidwill be kept out of contact with the" dies and heads or rolls.

What I claim as my invention is-- 1. In a wire-drawing machine, thecombination of a suitable framework, a tank carried thereby and havingan irregular bottom to produce different depths therein, said tankadapted to contain a liquid and a plurality of drawing heads or rollsarranged vertically in the shallower portions of said tank, the deeperportions thereof being adapted to receive and retain the dirt unaffectedby the circulation of liquid, due to the rotation of the drawing headsor rolls.

2. In a wiredrawing machine, a tank adapted to contain a lubricatingliquid and wire-drawing heads submerged therein, said tank being formedwith a portion of its bottom of one depth to support the wire-drawingheads, and with another, distinct portion of its bottom of a greaterdepth to receive and retain the dirt unaffected by the circulation ofthe liquid due to the rotation of the drawing heads or rolls.

3. In combination with a wire-drawing machine, a stringing mechanismcomprising a. gripping device movable alongthe framework of the machine,and a block serving as a die-holder and having a roll about which wireis adapted to pass adjustable along the path of travel of the grippingdevice.

t. In combination with a wire-drawing machine, having a runway along theedges of which a plurality of pairs of openings are provided, astringing mechanism, comprising a gripping device movable along theframe work of the machine in said runway and a block serving as adie-holder having a roll about which wire is adapted to pass, and a pairof pins which fit in any of said plurality of pairs of openings.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
